2 Intended use
The unit tests 2-, 3- and 4-wire sensors with digital switching output and an
operating voltage of at least 18VDC. For sensors with 2 switching outputs, the
switching outputs are connected to the quick-press terminal [IN] and tested one
after the other.
The function can be tested without removing the sensor. By means of the teach
function sensors with a teach input can be set.
The unit is intended for operation with a voltage supply ≤ 4.5 V. When the voltage
supply drops to a minimum of 3V, a stable output voltage of 18V is guaranteed.
Operation with rechargeable batteries is possible. For higher loads, connect a
standard 12V power supply observing the correct polarity.

3.1 Status LED
A permanent flashing of the green status LED (3) indicates low batteries. If the
output voltage drops to <16VDC, the unit automatically switches off.
When switching on while the batteries are low, the green status LED flashes twice
and the unit switches off.
uChange the batteries or rechargeable batteries.
4 Set-up
uInsert batteries or rechargeable batteries.
uAlternatively, connect a standard 12VDC power supply.
To switch the unit on, press the [ON/OFF] button briefly.
4.1 Insert batteries
uRemove all connected units.

uCarefully remove the protective cover.
uRemove the battery compartment cover by pulling it downwards.
uInsert 3x 1.5V batteries or rechargeable batteries with the poles in the direction
marked.
uPlace the cover back on the battery compartment.
uRefit the protective cover.
5 Electrical connection

Do not use a connection cable with integrated LED.
6 Operation
Test the connected sensor at the corresponding test surfaces of the unit.
• [Magnet] for sensors with magnetic operating principle
• [Reflection] for retro-reflective sensors
• [Induction] for sensors with inductive operating principle
6.1 Teach function
Test units with remote teach function by pressing the [Teach] button.

As long as [Teach] is being pressed, a voltage of 18V is applied to the
white quick-press terminal (T).
6.2 Automatic switch-off
The unit will be automatically switched off after 5 minutes when:
• not used (without load)
• no change of switching state in NPN/PNP operation
No automatic switch-off occurs if a sensor with push-pull function is connected.
6.3 Buzzer operation mode
The unit emits an acoustic signal (buzzer) during the sensor test.
In the delivery state, the buzzer is active on PNP.
Change of buzzer operation mode:
uSwitch on the unit.
uPress the [ON/OFF] button >2s.
wGreen status LED flashes:
• flashing 1x: buzzer active on PNP
• flashing 2x: buzzer active on NPN
• flashing 3x: buzzer OFF
The last selected state will be saved when the unit is switched off.
7 Maintenance, repair and disposal
If used correctly, no maintenance and repair measures are necessary.
Only the manufacturer is allowed to repair the unit.
uAfter use dispose of the device in an environmentally friendly way in
accordance with the applicable national regulations.
